Shadows are not soft suddenly when using sky sphere

I am trying to fix my shadows in my scene, because after closing it one time, I opened it again, and the shadows no longer looked soft. There was no ambient light in the scene. The shadows were just solid lines, straight from visible terrain to black, unlit sections where I can see nothing. You can see an example of the problem I am having below.

What happens if you rebuild your light?

It still looks exactly as it does right now.This is after building the light.
